Solution Overview
Problem
Current display devices for vehicles lack the ability to effectively transmit diverse driving information in a manner that intuitively conveys the depth and importance of safety-critical notifications, particularly in dynamic driving situations.
Innovation Solution
A display device comprising a first and second display, along with a tiltable light synthesizing unit that adjusts the reference angle based on driving conditions, allowing for the generation of three-dimensional visual information and varying the output position and size of displayed objects to enhance notification effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple displays are used to provide diverse driving information, then the quantity of information is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple display devices (first display and second display) into a single integrated display system. The light synthesizing unit merges the light paths from both displays, allowing diverse driving information to be presented through a unified optical path while maintaining the functional benefits of multiple information sources.
Solution Approach 2:
The light synthesizing unit serves multiple functions: it transmits light from the first display, reflects light from the second display, and directs both light paths toward the same viewing direction. This multi-functional component enables the system to provide diverse information without proportionally increasing overall system complexity.
2Adaptability or versatility
If a fixed display configuration is used, then the device complexity is reduced, but the adaptability to different driving situations deteriorates
Solution Approach 1:
The light synthesizing unit is designed to be tiltable with an adjustable reference angle, transforming the display system from a static configuration to a dynamic one. This allows the system to adapt to different driving situations by changing the angle at which information is presented, while the adjustment mechanism remains relatively simple.
3Ease of operation
If visual information is displayed without depth differentiation, then the ease of operation is improved, but the loss of information deteriorates
Solution Approach 1:
The patent introduces a depth dimension to the visual information display by using a tiltable light synthesizing unit. Information from the second display is reflected at an angle to create a sense of depth and layering, allowing critical safety information to be visually distinguished from general information without complicating the user interface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables more intuitive and effective transmission of driving information by creating a sense of depth and focus, preventing visual information from being obscured and improving the passenger's concentration on critical notifications.
Implementation Method 1
a light synthesizing unit disposed between the first and second displays and configured to transmit one of the first light and the second light and reflect another one so that the first light and the second light are directed to the same path
